ABSTRACT

A method and apparatus for allowing trials and court proceedings to occur in a virtual manner using a one way video session and a two way voice session are disclosed. During the trials or court proceedings, the defendants and their testimony can be viewed by judges and jurors who remain in isolated rooms with their identities masked. Judges and attorneys can verbally intercede during the proceedings via a two way voice session but the video session for the duration of the trial is one way.

This application is a continuation of U.S. patent application Ser. No. 11/263,258, filed Oct. 31, 2005, which is currently allowed, and is herein incorporated by reference in its entirety.

The present invention relates generally to communication networks and, more particularly, to a method and apparatus for providing high security video session for trial procedures in communication networks, e.g., packet networks such as Service over Internet Protocol (SoIP) networks.

BACKGROUND OF THE INVENTION

As extremely high bandwidth access networks become more accessible to residential subscribers, they enable service providers of these networks to integrate voice, video, and data, thereby providing more convenience for end customers and creating new service opportunities. Due to the multi-service nature of these new services, networks need to provide additional functionalities to end customers to support integrated control of these different types of services. For instance, criminal trials today are increasingly unearthing a number of security issues. Both judges and juries may be exposed to threats as well as actual violence in courthouses around the world.

Therefore, a need exists for a method and apparatus for providing high security video session for trial procedures in a packet network, e.g., a SoIP network.

SUMMARY OF THE INVENTION

In one embodiment, the present invention enables trials and court proceedings to occur in a virtual manner using a one way video session and a two way voice session in which defendants and their testimony can be viewed by judges and juries who remain in isolated rooms with their identities masked. Judges and attorneys can verbally intercede during the proceedings via a two way voice session but the video session for the duration of the trial is one way.

DETAILED DESCRIPTION

To better understand the present invention, FIG. 1 illustrates communication architecture 100 having an example network, e.g., a packet network such as a VoIP network related to the present invention. Exemplary packet networks include Internet protocol (IP) networks, asynchronous transfer mode (ATM) networks, frame-relay networks, and the like. An IP network is broadly defined as a network that uses Internet Protocol to exchange data packets. Thus, a VoIP network or a SoIP (Service over Internet Protocol) network is considered an IP network.

In one embodiment, the VoIP network may comprise various types of customer endpoint devices connected via various types of access networks to a carrier (a service provider) VoIP core infrastructure over an Internet Protocol/Multi-Protocol Label Switching (IP/MPLS) based core backbone network. Broadly defined, a VoIP network is a network that is capable of carrying voice signals as packetized data over an IP network. The present invention is described below in the context of an illustrative VoIP network. Thus, the present invention should not be interpreted to be limited by this particular illustrative architecture.

The customer endpoint devices can be either Time Division Multiplexing (TDM) based or IP based. TDM based customer endpoint devices 122, 123, 134, and 135 typically comprise of TDM phones or Private Branch Exchange (PBX). IP based customer endpoint devices 144 and 145 typically comprise IP phones or IP PBX. The Terminal Adaptors (TA) 132 and 133 are used to provide necessary interworking functions between TDM customer endpoint devices, such as analog phones, and packet based access network technologies, such as Digital Subscriber Loop (DSL) or Cable broadband access networks. TDM based customer endpoint devices access VoIP services by using either a Public Switched Telephone Network (PSTN) 120, 121 or a broadband access network via a TA 132 or 133. IP based customer endpoint devices access VoIP services by using a Local Area Network (LAN) 140 and 141 with a VoIP gateway or router 142 and 143, respectively.

The access networks can be either TDM or packet based. A TDM PSTN 120 or 121 is used to support TDM customer endpoint devices connected via traditional phone lines. A packet based access network, such as Frame Relay, ATM, Ethernet or IP, is used to support IP based customer endpoint devices via a customer LAN, e.g., 140 with a VoIP gateway and router 142. A packet based access network 130 or 131, such as DSL or Cable, when used together with a TA 132 or 133, is used to support TDM based customer endpoint devices.

The core VoIP infrastructure comprises of several key VoIP components, such the Border Element (BE) 112 and 113, the Call Control Element (CCE) 111, VoIP related Application Servers (AS) 114, and Media Server (MS) 115. The BE resides at the edge of the VoIP core infrastructure and interfaces with customers endpoints over various types of access networks. A BE is typically implemented as a Media Gateway and performs signaling, media control, security, and call admission control and related functions. The CCE resides within the VoIP infrastructure and is connected to the BEs using the Session Initiation Protocol (SIP) over the underlying IP/MPLS based core backbone network 110. The CCE is typically implemented as a Media Gateway Controller or a softswitch and performs network wide call control related functions as well as interacts with the appropriate VoIP service related servers when necessary. The CCE functions as a SIP back-to-back user agent and is a signaling endpoint for all call legs between all BEs and the CCE. The CCE may need to interact with various VoIP related Application Servers (AS) in order to complete a call that require certain service specific features, e.g. translation of an E.164 voice network address into an IP address.

In order to illustrate how the different components operate to support a VoIP call, the following call scenario is used to illustrate how a VoIP call is setup between two customer endpoints. A customer using IP device 144 at location A places a call to another customer at location Z using TDM device 135. During the call setup, a setup signaling message is sent from IP device 144, through the LAN 140, the VoIP Gateway/Router 142, and the associated packet based access network, to BE 112. BE 112 will then send a setup signaling message, such as a SIP-INVITE message if SIP is used, to CCE 111. CCE 111 looks at the called party information and queries the necessary VoIP service related application server 114 to obtain the information to complete this call. In one embodiment, the Application Server (AS) functions as a SIP back-to-back user agent. If BE 113 needs to be involved in completing the call; CCE 111 sends another call setup message, such as a SIP-INVITE message if SIP is used, to BE 113. Upon receiving the call setup message, BE 113 forwards the call setup message, via broadband network 131, to TA 133. TA 133 then identifies the appropriate TDM device 135 and rings that device. Once the call is accepted at location Z by the called party, a call acknowledgement signaling message, such as a SIP 200 OK response message if SIP is used, is sent in the reverse direction back to the CCE 111. After the CCE 111 receives the call acknowledgement message, it will then send a call acknowledgement signaling message, such as a SIP 200 OK response message if SIP is used, toward the calling party. In addition, the CCE 111 also provides the necessary information of the call to both BE 112 and BE 113 so that the call data exchange can proceed directly between BE 112 and BE 113. The call signaling path 150 and the call media path 151 are illustratively shown in FIG. 1. Note that the call signaling path and the call media path are different because once a call has been set up between two endpoints, the CCE 111 does not need to be in the data path for actual direct data exchange.

In order to illustrate how the different components operate to support a VoIP call, the following call scenario is used to illustrate how a VoIP call is setup between two customer endpoints. A customer using IP device 144 at location A places a call to another customer at location Z using TDM device 135. During the call setup, a setup signaling message is sent from IP device 144, through the LAN 140, the VoIP Gateway/Router 142, and the associated packet based access network, to BE 112. BE 112 will then send a setup signaling message, such as a SIP-INVITE message if SIP is used, to CCE 111. CCE 111 looks at the called party information and queries the necessary VoIP service related application server 114 to obtain the information to complete this call. In one embodiment, the Application Server (AS) functions as a SIP back-to-back user agent. If BE 113 needs to be involved in completing the call; CCE 111 sends another call setup message, such as a SIP-INVITE message if SIP is used, to BE 113. Upon receiving the call setup message, BE 113 forwards the call setup message, via broadband network 131, to TA 133. TA 133 then identifies the appropriate TDM device 135 and rings that device. Once the call is accepted at location Z by the called party, a call acknowledgement signaling message, such as a SIP 200 OK response message if SIP is used, is sent in the reverse direction back to the CCE 111. After the CCE 111 receives the call acknowledgement message, it will then send a call acknowledgement signaling message, such as a SIP 200 OK response message if SIP is used, toward the calling party. In addition, the CCE 111 also provides the necessary information of the call to both BE 112 and BE 113 so that the call data exchange can proceed directly between BE 112 and BE 113. The call signaling path 150 and the call media path 151 are illustratively shown in FIG. 1. Note that the call signaling path and the call media path are different because once a call has been setup up between two endpoints, the CCE 111 does not need to be in the data path for actual direct data exchange.

Media Servers (MS) 115 are special servers that typically handle and terminate media streams, and to provide services such as announcements, bridges, transcoding, and Interactive Voice Response (IVR) messages for VoIP service applications.

Note that a customer in location A using any endpoint device type with its associated access network type can communicate with another customer in location Z using any endpoint device type with its associated network type as well. For instance, a customer at location A using IP customer endpoint device 144 with packet based access network 140 can call another customer at location Z using TDM endpoint device 123 with PSTN access network 121. The BEs 112 and 113 are responsible for the necessary signaling protocol translation, e.g., SS7 to and from SIP, and media format conversion, such as TDM voice format to and from IP based packet voice format.

The network shown in FIG. 1 can be extended to become a SoIP network that supports multi-service applications including, but not limited to, video services. FIG. 2 illustrates a communication architecture 200 having an example network, e.g., a packet network such as a SoIP network related to the present invention. A SoIP network supports multi-service applications including voice, data, and video services. In one embodiment, a SoIP network that supports video services is described below. In this SoIP network, voice services supported include, but are not limited to, VoIP services; data services supported include, but are not limited to, Instant Messaging (IM), electronic mail (email), internet access services, or any other IP based applications; and video services include, but are not limited to, Video on Demand (VoD), broadcast video, and video conferencing services.

A SoIP network that supports video services comprises an intelligent multi-service endpoint device connected via packet access networks to a service provider's SoIP core infrastructure employing Internet Protocol (IP) and/or Multi-Protocol Label Switching (MPLS) Protocols. Broadly defined, a SoIP network is a network that is capable of carrying voice, video, and data signals as packetized data over an IP network. The present invention is described below in the context of an illustrative SoIP network that supports video services. Thus, the present invention should not be interpreted to be limited by this particular illustrative architecture.

Video endpoint device 232 and 233 are IP based intelligent multi-service endpoint device supporting voice, video, and data applications. Video endpoint device 232 and 233 are signaling endpoints of application sessions, e.g. a VoIP session endpoint, an instant messaging endpoint, or a video session endpoint. In one embodiment, a video endpoint device is a standalone device that can be connected to home electronic appliances such as, but is not limited to, telephone 234 and 235, TV 236 and 237, or Personal Computer (PC) 238 and 239. In another embodiment, a video endpoint device can be integrated with a TV, a PC, or any home appliances with a display.

The access networks are packet based. Packet based access networks 230 and 231 use, but are not limited to, Frame Relay, ATM, Ethernet, IP, DSL or Cable broadband access network technologies to interconnect a video endpoint device to a SoIP network that supports video services.

The core SoIP infrastructure that supports video services comprises of several key components, such the Border Element (BE) 212 and 213, the Call Control Element (CCE) 211, SoIP related Application Servers (AS) 214, Media Servers (MS) 215, Session Controller (SC) 241, Video of Demand (VoD) Servers 242, Broadcast Servers (242), and Instant Messaging (IM) Servers 243. A BE resides at the edge of the SoIP core infrastructure and interfaces with customers endpoints over various types of access networks. The functions supported by a BE include those supported by a BE as previously described in network 100 and FIG. 1. In addition, in a SoIP network that supports video services, a BE also serves as a gateway between a video endpoint device used by a subscriber and the SoIP core network that supports video services. All application sessions initiated by a SoIP subscriber must gain entry to the SoIP core network via a BE. The functions supported by a CCE and a MS are the same as those previously described in network 100 and FIG. 1. A Session Controller (SC) resides within the SoIP infrastructure and is connected to the BEs using an IP based signaling protocol such as, but is not limited to, Session Initiation Protocol (SIP). A SC is responsible for setting up all application session requests, such as VoIP call requests, video session requests, or data session requests, originated by a customer within the network and interacts with, if necessary, the appropriate SoIP related AS in order to complete an application session that requires certain service specific features originated by a customer. A SC also keeps track of all sessions initiated by a customer for session management and billing purposes as well. The functions supported by a SoIP related AS include those supported by a VoIP AS as previously described in network 100 and FIG. 1. In addition, a SoIP AS also supports all video specific application features. A VoD Server is responsible for supporting video on demand video session requests originated by a customer and sends the requested streaming video contents, such as a movie, to the customer. A Broadcast Server is responsible for supporting broadcast video session requested originated by a customer and sends streaming broadcast video contents, such as TV channels, to the customer. The VoD Server and the Broadcast Server sends streaming video contents to video endpoint devices using compression technologies including, but are not limited to, Moving Picture Experts Group (MPEG) 2, MPEG 4, MPEG 7, MPEG 21. An IM Server is responsible for supporting IM applications involving multiple users. Instant Messaging is a form of electronic communication that involves immediate typed text correspondence between two or more users over the Internet who are online simultaneously. IM is a text-based computer conference over the Internet between two or more people who are online at the same time.

In order to illustrate how the different components in a SoIP network operate to support video services, the following scenarios are used to illustrate how voice, data, and video sessions are setup between the SoIP network and a video endpoint. In one embodiment, a customer using video endpoint device 232 at location A places a VoD session request to the SoIP network that supports video services using TV 236. During the session initiation, a setup signaling message is sent from video endpoint device 232 to BE 212 using signaling path segment 250. BE 212 will then send a setup signaling message, such as a SIP-INVITE message if SIP is used, to SC 241 using signaling path segment 251. SC 241 processes the session requests and forwards the request to the appropriate server for further processing. In this case, the request is a VoD session; therefore, the request will be forwarded to VoD Server 242 using signaling path segment 252. SC 241 may interact with AS 214 using signaling path segment 259 to verify customer's subscription information or to retrieve video specific applications or data in order to complete the session request. Once the VoD session is verified, VoD Server 242 sends the requested VoD streaming contents to BE 212 using data path segment 262. BE 212 then forwards the requested VoD streaming contents to video endpoint 232 using data path segment 260. Similarly, a customer at location Z using TV 237 connected to video endpoint 233 can request a VoD session via SC 241 with streaming VoD contents sent by VoD Server 242. Note that a VoD server may be placed closer to end users in a packet access network to serve video endpoints in an alternative embodiment.

In another embodiment, a customer using video endpoint device 232 at location A places a broadcast video session request to the SoIP network that supports video services using TV 236. During the session initiation, a setup signaling message is sent from video endpoint device 232 to BE 212 using signaling path segment 250. BE 212 will then send a setup signaling message, such as a SIP-INVITE message if SIP is used, to SC 241 using signaling path segment 251. SC 241 processes the session requests and forwards the request to the appropriate server for further processing. In this case, the request is a broadcast video session for a particular premium TV channel; therefore, the request will be forwarded to Broadcast Server 243 using signaling path segment 253. SC 241 may interact with AS 214 using signaling path segment 259 to verify customer's subscription information or to retrieve video specific applications or data in order to complete the session request. Once the broadcast session is verified, Broadcast Server 243 sends the requested broadcast video streaming contents to BE 212 using data path segment 263. BE 212 then forwards the requested broadcast video streaming contents to video endpoint 232 using data path segment 260. Similarly, a customer at location Z using TV 237 connected to video endpoint 233 can request a broadcast video session via SC 241 with streaming broadcast video contents sent by Broadcast Server 243. Note that a Broadcast server may be placed closer to end users in a packet access network to serve video endpoints in an alternative embodiment.

In another embodiment, a customer using video endpoint device 232 at location A places an IM session request to the video network using PC 238. During the session initiation, a setup signaling message is sent from video endpoint device 232 to BE 212 using signaling path segment 250. BE 212 will then send a setup signaling message, including login and password information of the user, to SC 241 using signaling path segment 251. SC 241 processes the session requests and forwards the request to the appropriate server for further processing. In this case, the request to sign on an IM session; therefore, the request will be forwarded to IM Server 244 using signaling path segment 254. SC 241 may interact with AS 214 using signaling path segment 259 to verify customer's subscription information or to retrieve IM specific applications or data in order to complete the session request. Once the IM session is verified, IM Server 244 establishes the requested IM data path to video endpoint 232 via BE 212 using data path comprising data path segment 260 and 264. Similarly, a customer at location A using TV 236 connected to video endpoint 232 or a customer at location Z using PC 239 or TV 237 connected to video endpoint 233 can request an IM session via SC 241 with IM functions provided by IM Server 244.

In another embodiment, a customer using video endpoint device 232 at location A places a VoIP session request destined to video endpoint device 233 via the SoIP network that supports video services using telephone 234. During the session initiation, a setup signaling message is sent from video endpoint device 232 to BE 212 using signaling path segment 250. BE 212 will then send a setup signaling message, such as a SIP-INVITE message if SIP is used, to SC 241 using signaling path segment 251. SC 241 processes the session requests and forwards the request to the appropriate server for further processing. In this case, the request is a VoIP session for a call destined to a called party at location Z; therefore, the request will be forwarded to CCE 211 using signaling path segment 255. CCE may interact with AS 214 using signaling path segment 259 to verify customer's subscription information or to retrieve VoIP specific applications or data in order to complete the session request. The signaling flows to establish a VoIP call between video endpoint device 232 and 233 is similar to those described previously in network 100 and FIG. 1. In one embodiment, the Application Server (AS) functions as a SIP back-to-back user agent. Since BE 213 needs to be involved in completing the call; CCE 211 sends another call setup message, such as a SIP-INVITE message if SIP is used, to BE 213 using signaling path segment 257. Upon receiving the call setup message, BE 213 forwards the call setup message, via packet access network 231 to video endpoint device 233 using signaling path segment 258. Video endpoint device 233 then identifies telephone 235 and rings that telephone. Once the call is accepted at location Z by the called party, a call acknowledgement signaling message, such as a SIP 200 OK response message if SIP is used, is sent in the reverse direction back to the CCE 211. After the CCE 211 receives the call acknowledgement message, it will then send a call acknowledgement signaling message, such as a SIP 200 OK response message if SIP is used, toward the calling party at location A using signaling path comprising signaling path segment 256 and 250 via BE 212. In addition, the CCE 211 also provides the necessary information of the call to both BE 212 and BE 213 so that the call data exchange can proceed directly between BE 212 and BE 213. CCE 211 also provides the call completion status of a VoIP call to SC 241. The call media path comprising media path segment 260, 261, and 265 are illustratively shown in FIG. 2. Note that the call signaling path and the call media path are different because once a call has been setup up between two video endpoint devices, SC 241 and CCE 211 does not need to be in the data path for actual direct data exchange.

As extremely high bandwidth access networks become more accessible to residential subscribers, they enable service providers of these networks to integrate voice, video, and data, thereby providing more convenience for end customers and creating new service opportunities. Due to the multi-service nature of these new services, networks need to provide additional functionalities to end customers to support integrated control of these different types of services. For instance, criminal trials today are increasingly unearthing a number of security issues. Both judges and juries are exposed to threats as well as actual violence in courthouses around the world.

To address this need, the present invention enables trials and court proceedings (broadly defined as judicial proceedings) to occur in a virtual manner using a one way video session and a two way voice session in which defendants and their testimony can be viewed by judges and juries who remain in isolated rooms with their identities masked. Judges and attorneys can verbally intercede during the proceedings via a two way voice session but the video session for the duration of the trial is one way.

FIG. 3 illustrates an example 300 of providing high security video session for trial procedures in a packet network, e.g., a SoIP network, of the present invention. In FIG. 3, a trial is to be conducted between two locations, location A and location Z. The judge and jurors are located at location A while the defendants and the attorneys are located at location Z. Court official can use TV 339 to establish a secure trial application session between location A and location Z. The secure trial application session is sent from video endpoint device 332 to SC 341 using flow 350. Upon receiving the secure trial application session request, SC 341 sends a one way video session request to Video Conference Server 342 using flow 351 to establish the requested one way video session between location A and location Z. Upon receiving the one way video session request, Video Conference Server 342 forwards the video session request to video endpoint device 333 using flow 352 to complete the establishment of the requested one way video session. Note that the direction of the video flow can be specified during the secure trail application session setup phase. The video flow is always set in the direction from location Z to location A. Once the one way video session is established, video signal captured by video camera 337 will be sent via video endpoint devices 333 and 332 to TV 339 using the one way flow 360. Court officials at location A can control video camera 337 to zoom and scan as needed. Since the video session is a one way session, only the court officials at location A can control the camera functions.

Thus, in accordance with the present invention, locations A and Z may not even be in the same building. Furthermore, the present invention can be extended to more than two locations, e.g., the judge may actually be at a different location (e.g., a third location) from the jurors, and so on.

SC 341 also sends a VoIP session request to CCE 343 using flow 353 to establish the requested VoIP session between location A and location Z. Upon receiving the VoIP session request, CCE 343 forwards the VoIP session request to video endpoint device 333 using flow 354 to complete the establishment of the requested VoIP session. Note that the VoIP session is a two way voice session between location A and location Z. Once the VoIP session is established, voice communications between the telephone 336 and telephone 338 can proceed over the VoIP media path via video endpoint devices 333 and 332 using flow 361.

FIG. 4 illustrates a flowchart of a method 400 for providing high security video session for trial procedures in a packet network, e.g., a SoIP network, of the present invention. Method 400 starts in step 405 and proceeds to step 410.

In step 410, the method receives a secure trial application session request from a subscriber between two specified locations. For example, the secure trial application session request is received by a SC.

In step 420, the method establishes a one way video session between the two specified locations. The SC sends a one way video session request to a Video Conference Server to establish the requested one way video session. The direction of the video signal flow is also specified by the subscriber who initiates the secure trial application session. The direction of the video flow is always in the direction from the location where the defendant resides to the location where the judge and the jurors reside.

In step 430, the method establishes a two way VoIP session between the two specified locations. The SC sends a VoIP session request to a CCE to establish the requested two way VoIP session between the two specified locations.

In step 440, the method allows the court proceedings to be conducted, e.g. the one way video signal and the two way voice conversations are sent over the network to enable communications.

In step 450, the method checks if video camera adjustment commands are received from the controlling party of the one way video session. Camera adjustment functions allow the controlling party to zoom and scan as needed. The camera adjustment command is received by a video endpoint device connected to the video camera and sent to the video camera to execute the requested adjustments. If video camera adjustment commands are received, the method proceeds to step 460; otherwise, the method proceeds to step 470.

In step 460, the method executes the received adjustment commands. The camera adjustment commands, such as zoom and scan, are executed by the camera when the commands are received.

In step 470, the method checks if a secure trial session termination signal has been received. The session termination signal is received by the SC. If a trial session termination signal has been received, the method proceeds to step 480; otherwise, the method proceeds back to step 440.

In step 480, the method terminates the one way video session and the two way VoIP session. The sessions are terminated by the SC. The method ends in step 490.

FIG. 5 depicts a high level block diagram of a general purpose computer suitable for use in performing the functions described herein. As depicted in FIG. 5, the system 500 comprises a processor element 502 (e.g., a CPU), a memory 504, e.g., random access memory (RAM) and/or read only memory (ROM), a high security video session for trial procedures module 505, and various input/output devices 506 (e.g., storage devices, including but not limited to, a tape drive, a floppy drive, a hard disk drive or a compact disk drive, a receiver, a transmitter, a speaker, a display, a speech synthesizer, an output port, and a user input device (such as a keyboard, a keypad, a mouse, and the like)).

It should be noted that the present invention can be implemented in software and/or in a combination of software and hardware, e.g., using application specific integrated circuits (ASIC), a general purpose computer or any other hardware equivalents. In one embodiment, the present high security video session for trial procedures module or process 505 can be loaded into memory 504 and executed by processor 502 to implement the functions as discussed above. As such, the present high security video session for trial procedures process 505 (including associated data structures) of the present invention can be stored on a computer readable medium or carrier, e.g., RAM memory, magnetic or optical drive or diskette and the like.
